FINISH-REMOVER.

No Drawing.

To all whom it may concern:

Be it known that I, GARLETON'ELLIS, a citizen of the United States, and resident of Larchmont, in the county of Westchester and State of New York, have made a certain new and useful Invention Relating to Finish-Removcrs, of which the. following is a specification, this application comprising divisional subject-matter taken from my copending application, No. 364,749, filed March 27, 1907.

This invention relates to finish removers and relates es *cially to removers comprising carholic, cresylic or analogous acid bodics combined with suitable proteid palliativcs by which their corrosive or caustic ac tion may he neutralized.

Carbolic and cresylic acid and their higher homologues, guai acol, beechwood tar acid and other acid bodies of similar character derived from wood, coal, etc., by destructive distillation, including creosotes derived from wood and coal tar, shale oil and blast furnace products are sometimes desirable in removers that are used under extreme service conditions because of their energetic loosen ing action on many paints and finishes. These materials are, however, disadvantageous because of their caustic and corrosive action on the workmen and finish surfaces to whichthey are appliedunder certain circumstances. By the use of suitable palliative material, however, such corrosive prop erties may be mitigated and neutralized Without destriying the desirable loosening action on the finish and the remover rendered much more satisfactory in its action. Proteid bodies have a desirable pallative action of this character, albumen and gelatin forming when stirred into carbolic acid a desirable thick pasty mass, giving consistency to the remover as Well as having a very desirable palliative action on the carbolic acid or other acid bodies referredt-o, it being understood, of course that such acid bodies may be replaced to the extent of a few per cent. or so with other acids preferably of an organic character, such as tartaric, oxalic, lactic and other similar acids. In removers it is desirable to use in addition to such acid bodies and palliative material suitable finish Specification of Letters Patent.

solvent material preferably of a mixed char acter comprising true alcohols, such as rm thyl, ethyl, propyl, butyl, amyl, benzyl, and the like, preferably in. their commercial forms including denatured alcohol, as Well as various l-tetonic solvents including ace tone. methyl acetone. ace oil, as Well as aldehydes and of various kinds. Other desirable solvents are benzol and its homologues and the petroleum hydrocarbons, such as gasolei'ie, .wcll as carbonbisulfid, carboirtetrachh id, acetylene tetrachlorid and other chlorinated solvent com: pounds, turpentine, Wood turpentine, pine oil, resin spirits, spruce turpentine and the like.

Although not necessary in all cases, various stitlening materials, such as wood flour, starch. Whiting, fullers earth, magnesia, sodium silicate, intusorial earth, may be, used, and also waxy, soapy, or Intro-cellulose ifl'ening material, it being, of-course, understood that all the i redients are prefcrably thoroughly inc it Jed by agitation at the desired slight r3, 1 t tenmerature.

preparing remover .53 this ("carat-tor,

. gelatin, which may he uses if desired in the form of commercial glue bodies such as albu en be stirred into oarbolic, crcsylic or acid solventmaterial preferably when slightly heated, the rapidity of solution being promoted by slightly heating to 150 or 200 Fahrenheit so as to form a thick mass when 20')! of glue is dissolved in carbolic acid, for instance. The other finish solvent material mentioned may be incorporated with this proteid solution by agitation while still hot. Although this invention is not necessarily limited thereto, a suitable illustrative remover of this character may comprise 20 parts of a 20% solution of gelatin in carbolic acid, IQ-parts' of or other proteid *benzol, 8 parts of wood alcohol and 1 part of ceresin Wax. Another similar illustrative remover maycomprise 2 parts of a 20% solution of glue or gelatin in carbolic acid, 1 part of benzol and 1 part of Wood alcohol. Another illustrative remover may comprise 8 parts of a 20% solution of glue in cresylic acid, 4 parts of acetone and 1 part of turpentine. Another illustrative remover may comprise 1 part of a 25% solution of glue in carbolic acid and 1 part of wood alcohol. Another illustrative remover may comprise a solution of 5% of glue and 5% of albumen in carbolic acid. Another illustrative remover may comprise 1 part of glue, 5 parts of crude carbolic acid which contains, of course, considerable cresylic acid, 1 part of toluol, 1- part of gasolene, 3 parts of methyl acetone, 5 part of parafiin wax, f desired, and a part of concentrated lactic acid. Another illustrative remover may comprise 1' volume of a 10% solution of glue in glycerin combined with 2 volumes of carbolic acid with which may be combined, if desired, 3 volumes of benzol and 2 volumes of acetone. Of course the proportions'of the ingredients may be varied considerably and b using a greater roportion of the protei material considera ly thicker removers may be produced which are rather more desirable for some purposes.

Having described this invention in connection with a number of illustrative ingredients' and formulas, to the details of which disclosure the invention is not, of course, to be limited, what is claimed as new and what is desired to be secured by Letters Palterit is set forth in the appended claims.
